General Description The DM9051 is a fully integrated and cost-effective low pin count single chip Fast Ethernet controller with SPI interface, a 10/100M PHY and 4K Dword SRAM. It is designed with low power and high performance SPI interface that support 5V/3.3V IO tolerance. The DM9051 supports SPI interfaces to internal memory accesses for various processors. The PHY of the DM9051 can interface to the UTP3, 4, 5 in 10Base-T and UTP5 in 100Base-TX with HP Auto-MDIX. It is fully compliant with the IEEE 802.3u Spec. Its auto-negotiation function will automatically configure the DM9051 to take the maximum advantage of its abilities. The DM9051 also supports IEEE 802.3x fullduplex flow control. 3.
